I'm having a small issue that I'm sure is an easy fix for someone. When we had our older Exchange setup - if we restarted the exchange server, users would never know. It would simply disconnect, then reconnect, never bothering the users. However, now that we have Exchange 2010 and Windows 7 clients, every time we restart the exchange server, all users are bothered with a credentials log in screen and this can sometimes screw up their Outlook session, like it will get stuck until they restart outlook. Can someone help me on this issue? Thanks!

Hi! try to delete all vault records (Windows and Generic) related to your account from Windows credential manager, then run the Outlook client, enter your credentials at the password prompt and check the box "Remember my credentials". Your credentials will be saved in vault and Outlook should stop asking password. Make sure that Outlook in trying to connect to your account by default, in other case choose "Use another account" a the password prompt.You may use this guide http://plexhosted.com/billing/knowledgebase/223/Microsoft-Outlook-2010-does-not-save-your-password-Exchange-2010.html Hope it helps!
